MochaJew, that would be easy IF the game wasn't open-ended. The game would have to be extremely limited in nature for that to work. The couples would have to be the same for every single game sold, the same children born to the same couples. LDW would have to restrict the entire game (to the point that there would be NO replay value in it at all) in order to do the kind of family tree that you're speaking of.

But precisely because the game is open-ended it won't work. People play the game differently and also random villagers come up with each individual game, even the names are random each time you play the game.

They would have to limit the spontaneous and individuality of the VV line should they attempt to limit the characters like that and would probably lose an awful lot of customers (me included).

ETA: The situations you're speaking up are across the board in the game. Meaning that ALL ages are prohibited from procreation until the age of 18. And ALL of the women and men are prevented from embracing if they are the same sex. Since it's for every age or every sex it's easy for that code to be added in.......but not individual code for each villager.
